| 초록 | We investigated the performance of a jet loop reactor (JLR) with the two-fluid venturi-type swirl nozzle (TVSN) during experiment for ammonia removal by air stripping from a synthetic wastewater, and compared it with that of a JLR with the two-fluid venturi-type conventional nozzle (TVCN), with the variation of pH, liquid circulation rate (QL), and air flow rate (QG). Their performance levels were compared based on the ammonia removal efficiency and overall mass transfer coefficient (KLa). Investigated parameters in a JLR were pH (10-12), air flow rate (QG = 5-20 L min-1), and liquid circulation rate (QL = 25-35 L min-1). Throughout the experiment, the ammonia removal efficiency and KLa in a JLR with TVSN was higher than in a JLR with TVCN. This may be due to the enhanced turbulent intensity by swirling flow formed in the JLR with TVSN compared to that with TVCN. Further, we obtained higher KLa when pH, QL and QG were increased. In particular, KLa was increased more efficiently by increasing QG than by increasing pH and QL. |
